China’s Huawei has launched a series of lawsuits against Samsung in China and the USA alleging the company has infringed on its patents.

Huawei alleges a number of patent infractions, including the use of its 4G technologies in Samsung smartphones.

“We hope Samsung will stop infringing our patents and get the necessary license from Huawei, and work together with Huawei to jointly drive the industry forward,” says Ding Jianxing, President of Huawei’s Intellectual Property Rights Department in a statement.

Huawei claims that Samsung violates 11 standard-essential patents that it has filed.

The lawsuits were filed in U.S. Federal Court in California and in Shenzhen, the Chinese city where Huawei is based.
